Apple Paper: Calculator Keystroke For The HP-10BII
CALCULATOR KEYSTROKES FOR THE HP-10BII
[pic]
******* NOTE: The HP calculators come from the factory with the PMTS/YR set to 12. Change this setting to 1 PMT/YR by going to #6 below. Change this setting before you do any of the time value of money problems!!!! You only have to change the PMT/YR setting one time! *********
GENERAL: Note that every HP-10BII calculator key has two functions, the main ones are in WHITE LETTERS and a second function in ORANGE. To access the second function, you simply enter the ORANGE key first, and then press the key to access the function in ORANGE. There is also a PURPLE button, which accesses some statistical functions that we will not be using in this class.
In the examples below, the slash symbol: / is used to separate keystrokes
1. SETTING THE NUMBER OF DECIMAL PLACES:
Orange Key / = Key (DISP) / Number of desired decimal places
Examples:
Orange Key / = / 2 (to set display to two places, good for bond prices, e.g. $975.42)
Orange Key / = / 4 (to set display to four places, good for ex-rates, e.g. $1.5074 / £)
NOTE: Setting to two decimal places is not appropriate when calculating answers involving certain percentages or interest rates. For example, suppose your answer is an interest rate: .0851, or 8.51%. If your calculator is set to two decimal places, it will round your answer to .09 or 9%, which is almost .5% away from 8.51%. Be sure in this case that you set your calculator to display three or four decimal places, since 9% would not qualify for full credit when the true answer is 8.51%!! With experience, you will get used to changing the decimal display to the appropriate setting, based on the problem. 2. CLEARING THE CALCULATOR
To clear the calculator display (screen) only, use the C key (bottom left corner). This will NOT clear any of the financial registers, memory registers, or statistical registers.
To clear EVERYTHING (all registers), Enter the ORANGE KEY and then the C key to
